Let the hive mind of Engadget get that for you.
"I'm pretty much a complete noob when it comes to camera stuff. My wife loves to take pictures, though. So much so that she literally wore out her first point and shoot camera, and the Kodak Z712 I bought for her less than two years ago is starting to act up as well. To compound the matter, we are expecting our first born sometime next year. I fear the Kodak just isn't going to cut it any longer. What would be the best starter DSLR to get? She hates missing photo opportunities due to camera 'lag' so speed would definitely be at the top of the list. Photo quality and features would be next. Price should be no more than $800. I'm not interested in video capabilities."
You must be thinking of the Honda system, which is probably considered parallel. Motor is attached permanently to engine and they always turn together (in parallel).
Series Hybrid usually means: Engine-Generator to charge battery, supply power. No Engine direct connection to the wheels. IE like the Volt.
Toyota system is generally considered Series-Parallel. I agree, this is a very versatile arrangement. It can do everything. Mix any amount of Engine/Motor. Certainly the best system for a small battery hybrid.
